INSTALLATION/OPERATION

INSTRUCTIONS

VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container indicates

that there may be some damage to the machine. If there is damage to both the container and machine, do not throw away the

container. The dishmachine has been inspected and packed at the factory and is expected to arrive to you in new, undamaged

condition. However, rough handling by carriers or others may damage the unit while in transit. If this situation occurs, do not

return the unit to Ecolab; contact the carrier and ask them to inspect the damage to the unit and to complete an inspection

report. You must contact the carrier within 48 hours of receiving the machine.

UNPACKING THE DISHMACHINE: Once the machine has been removed from the container, ensure that there are no miss-

ing parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact your Ecolab rep-

resentative immediately to have the missing item shipped to you.

LEVEL THE DISHMACHINE: The dishmachine is designed to operate while being level. This is

important to prevent any damage to the machine during operation and to ensure the best results

when washing ware. The unit comes with adjustable bullet feet, which can be turned using a pair

of channel locks or by hand if the unit can be raised safely. Ensure that the unit is level from side

to side and from front to back before making any connections.

PLUMBING THE DISHMACHINE: All plumbing connections must comply with all applicable local, state, and national plumb-

ing codes. The plumber is responsible for flushing the incoming water line prior to connecting it to remove all foreign debris that

may get trapped in the valves or cause an obstruction.

CONNECTING THE DRAIN LINE: The ES-2000HT drain requires a minimum of 2” NPT piping that is pitched at least 1/4” per

foot. There must also be an air gap between the machine drain line and the floor sink or drain. If a grease trap is required by

code, it should have a flow capacity of 5 gallons per minute.

WATER SUPPLY CONNECTION: Read the section entitled “PLUMBING THE DISHMACHINE” above before proceeding.

Install the water supply line (1/2” pipe size minimum) to the dishmachine line strainer using copper pipe. It is recommended

that a water shut-off valve be installed between the main supply and the machine to allow access for service. The water sup-

ply line must be capable of 20A5 PSI “flow” pressure at the recommended temperature indicated on the data plate.

A water pressure regulating valve (PRV) is included as a standard item on the ES-2000HT. The pressure of the incoming water

should be adjusted to 20A5 PSI (flow) by turning the adjustment screw on the top of the PRV (clockwise to increase pressure,

counter-clockwise to decrease pressure). This adjustment must only be done while the incoming water fill solenoid valve is

open.

Do not confuse static pressure with flow pressure. Static pressure is the line pres-

sure in a “no flow” condition (all valves and services are closed). Flow pressure

is the pressure in the fill line when the fill valve is opened during the cycle.

It is also recommended that a shock absorber (not supplied) be installed in the

incoming water line. This prevents line hammer (hydraulic shock), induced by the

solenoid valve, from causing damage to the equipment.

PLUMBING CHECK: Slowly turn on the water supply to the machine after con-

necting the incoming fill line and the drain line. Check for leaks and repair as

required. Leaks must be repaired prior to placing the machine in operation.

ELECTRICAL POWER CONNECTION: Electrical and grounding connections must comply with the applicable portions of the

National Electrical Code ANSI/NFPA 70 (latest edition) and/or other electrical codes.

Disconnect electrical power supply and lockout the disconnect switch to indicate that you are working on the circuit.

The dishmachine data plate is located on the right side front of the machine. Refer to the data plate machine voltage, total

amperage load and serial number.

To install the incoming power lines, open the lower control box by removing the

control box lid. Install 3/4” conduit into the pre-punched holes in the back of the

control box. Route power wires and connect to power block and grounding lug.

Install the service wires (L1, L2 & L3 (Where applicable)) to the appropriate ter-

minals as they are marked on the terminal block. Install the grounding wire into

the lug provided.

It is recommended that “DE-OX” or another similar anti-oxidation agent be used

on all power connections.

VOLTAGE CHECK: Apply power to the dishmachine. Note: Do not turn the

machine on. Check the incoming power at the terminal block and ensure it cor-

responds to the voltage listed on the data plate. If not, contact a qualified service

agency to examine the problem. Do not run the dishmachine if the voltage is too

high or low. Shut off the service breaker and mark it as being for the dishmachine.

Advise all personnel of any problems and of the location of the service breaker.

Replace the control box cover and tighten the screws.

OPERATIONAL START-UP & CHECK: Before proceeding with start-up, verify the following:

1. Open the doors and verify that the pump intake strainer is correctly installed in the sump.

2. Check that the upper and lower rinse arms are securely screwed into their receptacles.

3. Check that the plugs are securely screwed into the ends of both wash arms and the rinse arms.

4. Check that the wash arms are securely screwed into the stationary bases and that they rotate freely.

5. Verify that the drain stopper is correctly installed at the drain seat.

QUICK START GUIDE: After the initial installation of the machine:

1. Insert chemical feeder pump stiffeners into appropriate containers.

2. Turn on machine.

POWER UP: To energize electrically, proceed as follows:

A. Turn on electrical power supply at the circuit breaker.

B. Check voltage at incoming terminals L1, L2 & L3. The voltage measured at these points should match data plate voltage.

C. If voltages are in required range, close the control box cover.

3. Before enabling the booster heater, the booster heater tank must first be filled with water.

TO FILL BOOSTER HEATER WITH WATER:

4. Press and hold the manual fill switch on the right side of the control box until you hear water being sprayed from the rinse

arms, indicating that the rinse tank is filled with water.

TO ENABLE THE BOOSTER HEATER:

5. Connect the orange/white wire in the control box from the heater contactor to the orange/white wire on terminal board 2.

NOTE: Ensure the orange/white wires at the heater contactor are connected properly. They have been purposely

disconnected at the factory to avoid damage to the heater element when there is no water in the booster tank.

6. Run a few machine cycles to verify the correct operation of the machine.

Check for water leaks.

Verify that the rinse temperature is between 180°F and 195°F for the entire rinse sequence. If it is not, before adjusting the rinse

thermostat, verify that the incoming water temperature is 110°F minimum and that the incoming water flow pressure is 20A5 psi

(measured during the rinse sequence). Adjust the pressure regulating valve as necessary to achieve 20A5 psi.

TO FILL WASH TUB: To Fill Wash Tub depress the “On -Off” switch to the “On” position. Depress and hold Fill Switch until you

see water draining out from the bottom of the machine. Open door for 3 seconds and close, this will start machine cycle. Allow

machine to complete one cycle, and then check for proper water level.

Note: Water must be in the sump while the machine is running to avoid running the pump dry and causing damage to the pump

seal.

If the water level is not at the level noted above it will require adjustment. Check to ensure that the recommended water pres-

sure is being supplied to the machine (20 ±5 PSI is required). If the water pressure is correct then the fill valve control will need

adjustment. Use the following steps to adjust the timer.

A. Open control box cover

B. Locate the electronic timer.

C. Refer to the next page for adjustment to the electronic timer.

NOTE: The machine must run a complete cycle to drain and fill. If the machine is not allowed to drain, the water will build up

inside the tub. After the initial fill, the rinse water for the current cycle will become the wash water for the next cycle.

The dishmachine is now ready to proceed with the washing of dishes.

PREPARING DISHES: Preparation of the ware will help ensure good results and less re-washes. If not done properly the dish-

es will not be clean and will reduce the efficiency of the dishmachine.

The following steps should be followed to ensure good results:

A. Remove all scraps and gross soil into a garbage can.

B. Separate and pre-soak silverware.

C. Separate and pre-soak the egg and casserole dishes.

D. Scrape all ware with a brush or spatula.

E. Flush cups, bowls and glasses with running water.

F. Prewash dishware by soaking or spraying with a pre-rinse hose.

G. Place dishes and cups in dish rack. Cups should be upside down (so they don’t hold water).

H. Place glasses and flatware in their respective racks. Scatter flatware loosely in rack. Glasses should be placed upside down

in a properly sized rack. For optimal results, flatware should be washed twice, the first being horizontal, the second in a special

rack to hold flatware vertical.

DAILY MACHINE PREPARATION: Before proceeding with start-up, verify the following:

A. Open door and verify that the sump strainer is in place in the sump.

B. Verify that the drain stopper is in position.

C. Check that the plugs are securely screwed into the ends of all wash arms.

D. Check that the wash arms are securely screwed into the stationary bases and rotate freely.

E. Check levels in all chemical containers and replace if empty.

F. For initial fill, close doors then depress the “FILL” switch to the “FILL” position.

WASHING A RACK OF WARE:

A. Open doors, place a full rack into the machine, and close doors. Unit will start automatically.

B. After cycle is completed open doors and remove rack.

C. Place another full rack into the dishmachine, and close doors.

D. Dishmachine will repeat cycle.

SHUT DOWN AND CLEANING:

A. At the end of mealtime, move the “OFF/ON” switch to the “OFF” position.

B. Open doors and manually remove drain stopper to drain the unit.

C. Remove and clean upper and lower wash arms.

SECTION 3:

PREVENTATIVE MAINTENANCE

The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However,

this does not mean that some items will not wear out in time.

There are many things that operators can do to prevent catastrophic damage to the dishmachine. One of the major causes of

component failure has to do with prescrapping procedures. A dishmachine is not a garbage disposal; any large pieces of mate-

rial that are put into the machine shall remain in the machine until they are either broken up (after spreading out on your ware!)

or physically removed. Strainers are installed to help catch debris, but they do no good if they are clogged. Have operators reg-

ularly inspect the pan strainers to ensure (1) that they are free of soil and debris and (2) they are laying flat in the tub.

When cleaning out strainers, do NOT beat them on waste cans. The strainers are made of metal and can be forgiving; but once

severe damage is done, it is next to impossible for the strainer to work in the way it was designed to. Wipe out strainers with

a rag and rinse under a faucet if necessary. For stubborn debris, a toothpick should be able to dislodge any obstructions from

the perforations. Always ensure that strainers are placed back in the machine before operation and that they lay flat in the tub.

You may wish to contact your Ecolab representative in order to learn more about how your water hardness will effect the per-

formance of your machine. Hard water makes dishmachines work harder and decreases efficiency.

Again, it is important to remind operators that trying to perform corrective maintenance on the dishmachine could lead to larg-

er problems or even cause harm to the operator. If a problem is discovered; secure the dishmachine using proper shut down

procedures as listed in this manual and contact your Ecolab representative.

Some problems, however, may have nothing to do with the machine itself and no amount of preventative maintenance is going

to help. A common problem has to do with temperatures being too low. Verify that the water temperatures coming to your dish-

machine match the requirements listed on the machine data plate. There can be a variety of reasons why your water temper-

ature could be too low and you should discuss it with your Ecolab representative to determine what can be done.

By following the operating and cleaning instructions in this manual, you should get the most efficient results from your machine.

As a reminder, here are some steps to take to ensure that you are using the dishmachine the way it was designed to work:

1. Ensure that the water temperatures match those listed on the machine data plate.

2. Ensure that all strainers are in place before operating the machine.

3. Ensure that all wash and/or rinse arms are secure in the machine before operating.

4. Ensure that drains are closed/sealed before operating.

5. Remove as much soil from dishes by hand as possible before loading into racks.

6. Do not overfill racks.

7. Ensure that glasses are placed upside down in the rack.

8. Ensure that all chemicals being injected to machine have been verified as being at the correct concentrations.

9. Clean out the machine at the end of every workday as per the instructions in the manual.

10. Always contact your Ecolab representative whenever a serious problem arises.

11. Follow all safety procedures, whether listed in this manual or put forth by local, state or national codes/regulations.

TROUBLESHOOTING

This trouble-shooting guide will help identify failed components. Before replacing a component that has been identi-

fied as faulty, double-check the wiring to and from the component, to ensure that the problem is not first caused by a

loose or open connection.

Inspection, testing and repair of electrical equipment should be performed only by qualified service personnel. Certain proce-

dures in this section require electrical tests or measurements while power is applied to the machine. Exercise extreme caution

at all times. If test points are not easily accessible, disconnect power, attach test equipment and reapply power to test. When

replacing electrical parts, disconnect power at source circuit breaker.

Problem: Machine will not turn on.

1. No power to dishmachine.

a. Check that service disconnect supplying power to the machine is ON.

b. Measure voltage at terminal block in lower control box. If no voltage exists, or the voltage does not match the voltage indi-

cated on the machine's data plate, seek the assistance of a qualified electrician.

Rinse booster tank must be filled with water before the heater is enabled to prevent damage to the heater element.

Problem: The temperature of the rinse water is too low, or the wash is being extended too often (when this feature is

enabled).

1. Incoming water pressure and/or temperature are not within required specifications. Check the temperature of the incoming

water. It must be 110°F minimum. Check the flow pressure of the incoming water (observe the indication on the pressure

gauge on the incoming water line when the incoming water solenoid valve is open). The pressure must be between 15 and 25

psi.

2. Rinse tank temperature setting is too low, or heater element has been disabled. It should typically be set at approximately

185°F, depending on the operating parameters at the particular installation. Confirm that the heater element has been enabled.

3. The rinse tank heating element is faulty. Using a clamp-type amp probe, measure the amperage through each coil of the

heater element wires. The amperage should be approximately equal through each coil. If not, replace the heater element. An

alternate method of checking the heater element is to first disconnect power to the machine, and then disconnect all wires at

the heater element. Measure the resistance of each coil of the heater element. The resistance measurements should be

approximately equal through each coil.

Problem: Machine will not fill or rinse.

1. The incoming water line is blocked, preventing water from entering the machine. Check and, if necessary, clean the Y-strain-

er on the incoming water line.

2. The incoming water solenoid valve is faulty. Replace solenoid valve.

Problem: Wash pump motor will not run.

1. The wash pump motor is faulty. If you hear the contactor engage when you try to manually run the pump and the pump

does not run, the pump motor is faulty and must be replaced. The motor contains integral thermal overload protection devices.

If the motor becomes hot from excessive loads, these devices open the electrical circuit within the motor and prevent the motor

from running. Before replacing the motor, allow it to cool so that the overload devices can reset themselves, and then re-test

the motor. If the motor still does not run, replace the motor.

Problem: Machine runs with the doors open.

1. Door switch is faulty. Disconnect the door switch leads and check for continuity between the two leads when the doors are

open. If continuity, replace door switch.

Problem: Machine will not drain. Drain mechanism does not move up or down.

1. Loose wire connection. Verify that all wire connections are tight.

2. Drain hole may be obstructed. Remove the obstruction.

3. Drain rod bent or binding. Repair the rod, or replace as necessary.
